 * Just installed 2.6 and ran upgrade.php, and got this.
 * `Fatal error: Cannot redeclare validate_file() (previously declared in /home/
   cmwong/domains/wetcalamari.net/public_html/wp-includes/functions.php:2238) in/
   home/cmwong/domains/wetcalamari.net/public_html/wp-admin/includes/file.php on
   line 73`
 * the directory doesn’t contain file.php, and it didn’t come in the distro either.
   Am I missing something?

 * I am having the same problem on two different sites. Anyone have any ideas about
   how to fix it?

 * I would suggest deleting everything except /wp-content/ folder then upload WP2.6
   again.

 * I deleted everything except the wp-content folder and the config file and installed
   WP2.6 and it worked. Not sure what I did the first time but that sovled the problem.

 * I would always recommend you deleting everything and upload the new content instead
   of overwriting it.

 * Thanks, this worked for me. Any thoughts on which file was the culprit?

 * I still get this error after I’ve deleted wp-admin and wp-includes and the root
   files (and re-uploaded of course) for several times now.
 * I’ll try putting back 2.5 but I doubt that it will work.
